Abstract: The present disclosure belongs to the field of geological exploration, and particularly relates to a seismic acquisition system based on a frequency domain expansion MEMS sensor, aiming at solving the problem that vibration frequencies exceed the frequency range of the MEMS sensor due to strong vibrations and cross coupling of multi-frequency signals usually occurring in well logging while drilling. When the MEMS sensor suffers strong vibrations or the MEMS sensor that can be selected cannot ensure that the frequency requirement of a measurement signal is stably met, the frequency domain expander of the present disclosure expands the frequency domain of a detection signal, so that the MEMS sensor can measure strong vibrations and out-of-band frequencies to a certain extent, the application range of the seismic acquisition system is extended, and the anti-mutation capability of the seismic acquisition system is improved.

Abstract: The present invention provides a method and system for inserting advertisement content into a text message. The text message is sent from a first communication device by a subscriber to a recipient via a SMSC. The method for inserting advertisement content into the text message includes changing (302) original SMSC address of the text message. The method further includes receiving the text message (304) with the changed SMSC address. Further, the method includes inserting (306) at least one advertisement into the text message, where the at least one advertisement is selected from one or more advertisements. The method further includes directing the text message (308) with the at least one advertisement to the SMSC. Finally, the method includes providing a credit (310) to the subscriber for the text message.
